How to Secure Your Newton Business with a Master Key System
Whether you run a single office or a multi-tenant facility, a master key system gives you greater control and convenience—without compromising security.
Why Master Key Systems Matter for Newton Businesses
In Newton, businesses operate out of a variety of property types—from classic brick buildings in Newton Centre to office parks in Newton Corner. Regardless of your building’s size or layout, managing access is a top priority.
That’s where a master key system comes in. These systems allow different levels of access across your property. Employees can open only the doors they need, while management has a single master key for everything.
If you’re still using the same key for every door—or worse, juggling a keyring with ten different keys—it might be time to simplify.
What Is a Master Key System?
A master key system is a lock configuration that allows two or more keys to open one lock. There are typically three access levels:
- Change Key (Sub-Key): Opens only one specific door
- Master Key: Opens all the locks within a designated group or property
- Grand Master Key (Optional): Opens multiple properties or zones (ideal for larger campuses or multi-building sites)
With a properly designed master key system, you reduce key clutter while maintaining strict access control.
Benefits of Master Key Systems
✅ Increased Convenience
No more carrying a bulky set of keys or guessing which one fits where. One key gets you into every space you’re authorized to access.
✅ Enhanced Security
Give employees access only to the areas they need—nothing more. This reduces unauthorized access and protects sensitive zones.
✅ Cost Savings
Rekeying a large building every time an employee leaves can get expensive. With a master key setup, you often only need to rekey one cylinder.
✅ Emergency Access
In a fire, medical emergency, or security breach, management or first responders can access every area quickly.
✅ Scalable Design
Whether you’re operating out of a single suite or planning to expand, a master key system grows with your business.
